Let P and Q be two convex polygons with m and n vertices, respectively, which are specified by their cartesian coordinates in order. A simple \(O(m+n)\) algorithm is presented for computing the intersection of P and Q. Unlike previous algorithms, the new algorithm consists of a two-step combination of two simple algorithms for finding convex hulls and triangulations of polygons.
